要从队列中读取消息(在本例中最终涉及到从文件系统中读取数据，因为我们使用文件系统的JNDI标识符)，使用清单11中的代码。
To read the message from the queue (which in this case ultimately involves reading from the file system since we use the JNDI identifier for the file system), use the code in Listing 11.
当然，这些标识符仅相对于所使用的表或数据库是惟一的—其他表或数据库还可以使用它们。
Of course, these identifiers are only unique for the table or database they are used on - they can be reused by other tables and databases.
结果集是一个数组，该数组由0个或多个与数据库查询相匹配的行组成；结果集标识符只是一个值，您可以将该值传递给其它函数，以使它们能够使用结果集中的行。
A result set is an array consisting of 0 or more rows that match a database query; a result set identifier is simply a value that you pass to other functions to work with the rows in the result set.
我在应用程序中看到的一个问题是，工程师试图将数据库当作编程语言来使用，即通过使用具有逗号分隔的标识符的文本字符串来创建数组。
One problem I've seen with applications is when engineers attempt to use a database as though it were a programming language, creating arrays by using text strings with comma-separated identifiers.

然后，服务器可以使用这个标识符查找到所有复杂的状态(包括客户机应该无法访问的数据)，并提供有状态的行为。
The server can then use that identifier to look up all the complicated state (some of which the client shouldn't have access to!) and provide stateful behavior.
使用上述的一些技术，可以提取IP地址和惟一标识符，并把查找与您自己的数据库联系起来。
Using some of the techniques described, you can extract your dotted quads and unique identifiers, and link the lookups to your own databases.
在实现数据中心自动化过程中，必须使用一致、可重复且可靠的机制支持EWU标识符。
When implementing data center automation processes, it is imperative that consistent, repeatable, and reliable mechanisms be used to support this structure.
JNDI名是您的代码用来查找数据源的唯一标识符。本文的范例代码使用jdbc/OracleXADS 作为 JNDI 名。
The JNDI name is the unique identifier your code will use to lookup the data source; this article's example code uses jdbc/OracleXADS.
